we have about seven computers all running some version of windows from xp to 10. So's I can move files between them at will I habitually share all the drives. And, of course, every time I do I run into Microsoft's warning about sharing root drives. never worried me. but now we have this ransomware thing and there seems to be no protection. how should i set permissions and sharing on my drives across these computers so's I can enjoy easy of moving files and still be as safe from ransomware and whatever other threats as possible? The easiest thing would be if they were only shared for me as admin but that's not what happens, is it and even then I suppose ransomware logs in as admin so it'd be no protection against it. we have this wonderful big time professional file security thing in windows but it might as well not be there for all the good it seems to be to me. where am I wrong? what should I do?
